Final answer:
An investigator uses minimization or maximization techniques in an alternative question to encourage a suspect to choose between two options. Through incentives or perceived severity, this approach aims to elicit information from suspects in situations such as carrying illegal weapons or committing a more serious offense.
Step-by-step explanation:
When presenting an alternative question, the investigator seeks to encourage the suspect to choose between two options.
They could use either minimization techniques, which downplay the severity of one option to make it seem more acceptable, or maximization techniques, which magnify the potential consequences of the alternative to make the first option seem more favorable.
For example, an investigator might say, 'Did you break into the house because you were desperate for money, or was it just for the thrill of it?' The suspect is more likely to admit to the option that seems less severe.
In the context of an investigation where the suspects are apprehended for carrying an unlawful weapon and potentially committing armed robbery, an investigator might use the alternative question technique to try to pinpoint which suspect was involved in the more serious crime.
If the suspects are better off remaining silent to receive a minimal sentence, the investigator's challenge would be to provide incentives for them to speak, possibly by presenting one charge as less serious than the other.
